Does the efficiency of a motor depend on mass?

Physics

Practically yes

  • Efficiency=Output/input

So

If mass is more output may come less so it affects the efficiency practically

But thepritically it doesn't

Answer:

<u>Yes</u>

Explanation:

<u>Formula of motor efficiency</u>

  • η = Input Load (E₀)/ Output Load(E₁)

We know from simple physics that the energy of a body is directly proportional to its mass. Here, in the working of a motor, mass may not be involved directly, but the electrical energy required to provide a function will likely have more efficiency when working with lesser masses.

Describe the process of sexual reproduction in terms of the life cycle of cells.
umka2103 [35]
The first growth phase (G1): During the G1 stage, the cell doubles in size and doubles the number of organelles.

The synthesis phase (S): The DNA is replicated during this phase. In other words, an identical copy of all the cell’s DNA is made. This ensures that each new cell has a set of genetic material identical to that of the parental cell. This process is called DNA replication.

The second growth phase (G2): Proteins are synthesized that will help the cell divide. At the end of interphase, the cell is ready to enter mitosis.

Ted lifts a 10N weight at a height of 1.5 m in 1
masha68 [24]

Answer:

D. Ted expanded more power.

Explanation:

Given the following data;

For Ted.

Force = 10N

Height = 1.5m

Time = 1 seconds

To find Ted's power;

Power = workdone/time

But workdone = force * distance

Workdone = 10 * 1.5

Workdone = 15 Nm

Power = 15/1

Power = 15 Watts.

For Johnny.

Force = 10N

Height = 1.5m

Time = 2 seconds

To find Ted's power;

Power = workdone/time

But workdone = force * distance

Workdone = 10 * 1.5

Workdone = 15 Nm

Power = 15/2

Power = 7.5 Watts

Therefore, from the calculations we can deduce and conclude that Ted expanded more power.

At a speed of 60 mph, how far does your car travel in 3 seconds
Viefleur [7K]

One of the many random useless factoids that I carry around
in my head is the factoid that 60 miles per hour is equivalent
to exactly 88 feet per second.

So in three seconds at that speed, you would cover exactly

                       (3 x 88) = 264 feet.

What can be caused by nuclear explosions and can easily penetrate into the human body causing severe damage?
dedylja [7]

Answer:

Nuclear explosions produce air-blast effects similar to those produced by conventional explosives. The shock wave can directly injure humans by rupturing eardrums or lungs or by hurling people at high speed, but most casualties occur because of collapsing structures and flying debris.
